One method of matching that makes some sense is to use propensity
scores. Basically, you run a logistic regression with your two
"groups" as the dependent variable and your age, education, etc.
covariates. There are various articles that discuss the method, so do
a google search on something like...propensity matched pairs. There
are some algorithms out there, also, that use a little different
approach and weight the covariates so that you can get good matches
on, say, gender with a little latitude on the age variable.
